Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (6)

`build_utm_links`read-only	Adds utm_source, utm_medium (social by default), utm_campaign and optionally utm_content and utm_term to a link: one link per platform, or one for a source you name.
`check_caption`read-only	Counts a post's text the way Instagram, Facebook, YouTube, TikTok, LinkedIn and X count it, against each platform's limits: characters, X's weighted 280 (emoji 2, links 23), TikTok's UTF-16 2,200, YouTube's 100-character title and 5,000-byte description, Instagram's 5 hashtags and 20 mentions. Returns each platform's counts, limits and whether it fits.
`check_video`read-only	Says whether a video will post on each platform (as a Reel, Short or video, and as an Instagram or Facebook Story), from its technical facts: size in bytes, length, width and height, frame rate, video and audio codec, sample rate, container, HDR and whether the index is at the front. Returns a verdict per platform with each check's message.
`get_image_sizes`read-only	Returns recommended image sizes per platform (posts, Stories, covers, banners, thumbnails, profile pictures) with each size's source.
`get_platform_specs`read-only	Returns the limits for posting to Instagram, Facebook, YouTube, TikTok, LinkedIn and X (or one of them): text length and how it's counted, hashtags, video length, file size, shape, codecs, frame rate, Stories, photos per post and posts per day, with the date they were checked.
`get_safe_zones`read-only	Returns the margins to keep clear on a 1080×1920 vertical video for Instagram and Facebook Reels, TikTok and YouTube Shorts, where each app's buttons and captions sit, with sources.
